Does anyone know the science behind why blood helps with the decomposition process? Obviously there is something behind it since the Babylonians used camel blood and we are still using blood meal today.
Does the blood somehow start to grow the specific bacteria that are used in decomposition? Perhaps the blood also already has the bacteria that are needed. That is why using old compost or soil helps speed the process.
Are there any other ways to speed the composting process without adding soil or using commercial products?
